Simplified schematic showing the key components of the cellular iron import-export machinery. In cancer cells, a larger labile iron pool is maintained through the overexpression of the transferrin receptor TfR1, transporter DMT1, and STEAP metalloreductases, as well as through the downregulation of iron exporter FPN mediated by hormone hepcidin.
